Anyone who likes Entourage probably has a less-than-favorable impression of celebrity siblings. But you have to give Tony Rock a break — there are nine Rock siblings including Chris and Tony, but only two have managed to make it in comedy. There’s a reason the Rock brand of humor works: because it’s funny. Tony tackles racial prejudice (on the idea that black people are lazy: “We worked for this country for 400 years for free! We ain’t lazy, we on vacation!”), black people’s affinity for chicken (“When the bird flu comes around I’m gonna be immune to that shit!”) and, finally, his own perceptions of other races (“What the fuck is an Armenian? I thought that shit was a suit!”). Tony probably won’t be hosting any award shows any time soon, but he’s hardly a cheap imitation of his brother. 8 p.m. Thursday; 8 and 10:30 p.m. Friday and Saturday; 7:30 p.m. Sunday.
